I have had this engine for the past 12 years, one of the many engines I have collected since I got into the engine hobby in the early 1980s. It is a 1919 8 HP Associated Eight-Mule Team, serial no. 801932. My dad bought it from his neighbor in Omak, Wash., in 1992. Dad knew about the engine, as he had helped saw wood with it.

A quick look showed it was complete, down to the original gas tank, with the exception of the muffler and magneto. We took the buzz saw off the back and stored the engine out of the way. After looking at it for some time, I decided this past winter to make it one of my projects.

During the disassembly process, we found the moving parts were badly worn, as dried oil and sawdust stopped them from being lubricated. Even so, the crank was in good shape, although the crank babbitt caps were full of shims, so we adjusted them down. Much to our surprise, we found the rod bearings to be the brass originals. We replaced the pins and bushings during the restoration, also.

The engine had a spark plug conversion in place of the original magneto, so the hunt was on for a replacement. Once we located the correct Webster low-tension magneto, we sent it to Mark's Magneto Service in Lisbon, Conn. to be rebuilt. As for the igniter, I happened to have a spare lying around the shop. We then painted everything in aluminum or a dark shade of IHC red. The original-style lettering and pin striping was done by local expert Ken Fuhr.

Once we had the engine put back together and ready to go, my son, Herman Jr., helped turn it over, and in a great cloud of smoke, it started. A few minor adjustments later it settled down and ran like it most certainly did 85 years ago.
